I have literally never watched or read a review of ESO or Fallout 76.
I played both.
ESO fails at being a solid Elder Scrolls game because it’s tailored more toward an MMO experience. The writing is awful, and the quests are boring. The combat sucks, and the social features are abysmal given you can’t even share quests. Literally the only reason I could imagine anyone playing this game is because they want to grind out an MMO every day that’s set in the Elder Scrolls universe.
Fallout 76, I don’t even know where to start. Again, the MMO mechanics tear out everything good about Fallout games to deliver a bland, grindy MMO with bad combat.
It’s still open world in the sense that there are plenty of places you can go to and in any order without being gated through a linear story line.
Even if you were to ignore my advice, it wouldn’t be any more open world because travelling between these areas is always gated by loading screens.
My suggestion is merely to reduce the amount of loading screens between zones.
Instead of leaving constellation, loading Jameisom, getting on the train, loading the shipyard, entering your ship, loading the ship interior, taking off, loading space, going to your map, selecting warp to sol, loading sol, selecting a landing site on Cydonia, loading your ship interior on cydonia, leaving your ship, and loading cydonia.
I’m suggesting you fast travel straight from the lodge to cydonia. Cutting 7 loading screens down to 1.
Of course, I also recommend that you take time to explore the areas you’re in.
